Design outcomes

Primary

Measure	Time frame
determination of the benefit of the ATS Minimicrophone 2+ in directional microphone mode with regard to the speech reception threshold (SRT) in noise from bilaterally supplied CI recipients (BiCI group) in a restaurant scene as the difference between the SRT when using the Minimicrophone 2+ in directional microphone mode with both CP1000 CI sound processors with deactivated processor microphones and the SVS when exclusively using both CP1000 with activated directional microphone technology ForwardFocus	—
